'7 Claims. 1

My invention relates to a machine for making pro-built borders formattressts.

An important object of the invention is to provide a machine of theabove mentioned character for use in connection with a standard sewingmachine, which sewing machine may be readily applied in position andremoved therefrom, as

desired.

A further object of the invention is to provide a machine of the abovementioned character wherein the sewing machine is'held stationary andthe work is shifted longitudinally and laterally with respect'tov thesewing machine.

A further object. of the invention is to provide means for transverselyreciprocating the work with respect to the sewing machine and effectinan intermittent longitudinal feed of the work at the end of eachtransverse stroke.

A further object of the invention is to provide a machine of the abovementioned character which is of simplified construction andis'relatively inexpensive to manufacture and automatlo and reliable inoperation.

Other objects and advantages of the invention will be apparent duringthe'course of the following description.

on line 3-3 of Figure'2, the carriage being shifted to the left.

Figure 4 is a similar view with the carriage shifted to the right,

Figure 5 is a transverse section taken on line 5-5 of Figure 1, t

Figure 6 is .a vertical section taken on line 6-6 of Figure 5,

Figure '7 is a fragmentary plan view of the bore der produced bythenormal operation of the machine,

. Figure 8 is a similar view of the border produced by an adjustment ofthe machine, and,

Figure 9 is a similar view showing a border produced by a furtheradjustment of the machine. In the drawings, where for the purposeof.illustration is shown a preferred embodiment of my invention, thenumeral 20 designates a carriage which is'shiftable laterally and heldagainst longitudinal displacement. The :carriage comprises a lowerhorizontal framed I, supported bye riage.

" wheels 22, traveling upon stationary tracks '23.

The carriage further comprises a verticalframe 24, rigidly mounted uponthe horizontal frame, nearer one longitudinal edge thereof. Extendinginto the upperportion of the vertical frame 24 and above thehorizontalframe 2!, is a horizontal table top 25 which is stationary and supportedby legs .26 and diagonal braces 21. The table top 25 extends intothecentral open space of the vertical frame 24 and will clear this frameduring the transverse reciprocation of the car- Mounted upon thestationary top 25 isa sewing machine 28, of any well known or referredtype. This sewing machine includes the usual arm 29 and head 30. Thesewing machine is arranged upon the table top, so that the longitudinalaxis of the arm 29 extends transversely of the carriage 20 orlongitudinally of the direction of reciprocation of this carriage. Thesewing machine includes the usual reciprocatory needle and the usualpresser-foot used in-sewing quilting. The machine will sew the line ofstitching in any direction, dependingupon the movement of thejwork withrespect to the needle.

The conventional feed dog of the sewing machine may be removed asseparate meansare provided to feed the work longitudinally of thecarriage. Since the table 25 is stationary, 'thesewing machine is heldstationary. This construction is advantageous inasmuch as it eliminatesany special mounting for the sewing machine, as is done when the sewingmachine is reciprocated. It

also permits of the sewing machine beingreadily separated from the tabletop so that such sewing machine may be used for. other purposes-ifdesired or a diiferent sewing machine susbtituted therefor. The sewingmachine 28 may be driven continuously by a separate motor 3 I.

The carriage 20, embodies a shelf 32 upon which the folded ticking 33may be supported and this ticking is passed about guide rollers 34 and35, mounted upon the vertical frame 24. The'n-umeral 36 designates aroll of inexpensive fabric, such as tobacco cloth, cheesecloth, or thelike. The fabric 36 is passed about a guide roller 31 also mounted uponthe upper end of the vertical frame 24. The carriage further embodies ashelf 38 for supporting cotton wadding or batting 39, which is passedover the fabric 36, beneath the fabric 33 and over the guide roller 31.The fabrics 33 and 36 pass from the roller 31 in superposed relation andthe wadding or batting 36 is arranged between these fabrics, and theassembled fabrics and batting then pass beneath a transverse guideroller 40, arranged near and above the table top 25, to position theassembled work layers fiat upon the table top 25. The assembled layersof the Work will slide as a unit upon the table top, longitudinally ortransversely of the table top. The work discharges from the table top 25and passes between a pair of opposed feed rollers 4| and 42. Thevertical frame, at the discharge side of the feed rollers, may beequipped with a table top 43, for supporting the finished work whichwill discharge downwardly from the table top and may be collected in abox or basket 44. The feed rollers 4| and 42 are em ployed to feed thework longitudinally, intermittently, and the lower roller 42 is drivenfor this purpose, as will be explained. 1

Mounted within the central open space of the vertical and horizontalframes of the carriage 20 is a stationary horizontal base or beam 45.Mounted upon the stationary base 45 is afixed bearing 46, holdingahorizontal rotatable shaft '41, held against longitudinal-displacement. A companion fixed bearing48 is mounted upon thestationary base 45 and holds arotatable shaft 49, also held againstlongitudinal displacement.

Rigidly mounted upon the" shaft. 4? is a. sprocket --whee1 59 and asprocket wheel is rigidly mounted upon the shaft 49 and an endlesssprocket chain 52is. passed about these sprocket "wheels 50 and 5|.

The shaftsand .49 extend longitudinally of the frame 20,-whilethesprocket chain 52 extends transversely-of the carr iage,.as

shown. The shaft 41 is driven by gearing 53,

which in turn may be driven from a motor 54.

" Any suitable'type of speed reducing gearing-may be employed.

. In order that-the carriage 20 maybe reciprocat'ed transversely byth'e'conti'nuous travel of the endless chain 52 in one direction, thecarria'ge has a pair of spaced superposed horizontal bars 55 and 56rigidly secured thereto, and these bars extend transversely of thecarriageand longitudinally of the endless sprocket chain 52,

above and below the same. The bars-55 and 56 "reciprocate with thecarriage while the shafts 4-! and 49 remain in afixed location. The bar55 has a depending peg or extension 51 rigidly secured thereto and thebar- 56' has an upstanding peg or extension-58 rigidly securedith'ereto.

' The pegs 51 and 58 are vertical andiare longitudinally staggered withrespect to bars55 and 56,

This shaft is arranged" nearithe endless sprocket v, chain 52 and-isparallel therewith. The shaft 6| has a'sprocket wheel 62 rigidly securedthereto,

engaged by a sprocket chain 63,1enga'ging.a sprocket wheel 64', mountedupon a transverse shaft 65, supporting and'driving thelowerfeed roll 42.It might be'stated-that the shaft.26| "is intermittently turned and thisoperatesthe feed rollers 4|and 42 to intermittently feed the work.

Rigidly mounted upon the shaft6| is a disc v66, having four pins 6!rigidly secured thereto and extending axially thereof. These fourpinsare arranged 90- degrees apart; whereby the pins are disposed indiametrically .opposite pairs. -s"traight lea-r68 is rigidly mountediuponithe shaft 6| 'a'ridh'asa; pair;of diametrically oppositely arrange'd' pins- 69 rigidlymounted thereon and .ex-

66 and 68 are spaced longitudinally of the shaft 6| for a distancecorresponding generally to the length of the endless chain 52. Thesprocket chain 52 has horizontal transverse pins '19 and H rigidlysecured thereto and projecting laterally beyond same for co-action withthe pins 5? and 69, as will be explained.

The operation of the machine is as follows:

7 It will be assumed that the work has been passed beneath the presserfoot of the sewing machine and is engaged between the feed rollers Thesewing machine is constantly operating and the shaft 41 is continuouslydriven clockwise,,Figures 1, 2, 3 and 4, and counterclockwise, Figure 5.The pin 59 which is now at the lower rung of. the endless chain 52, isbrought into engagement with the lower peg 58, and the carriage isshifted to the extreme left, Figure 3.

'When this position is reached, the pin 59 travels about the sprocketWheel 5|, Figure 5, and dis- The carriage is now at rest and willremain. atrest until. the pin-59 engages behind the upper peg-51.-Whilethe carriage is thus at rest in the extreme left position, the pinI0 is traveling. downwardly about the sprocket wheel and will engagethe. pin 61, turning the disc 66, turning the shaft.6|,. which in turnturns the lower feed roller 42 to feed the work a step. By the time thepin 59 engages the upper peg 5l,-the pin 18 has moved thepin 6'! to thelowermost position and the horizontal travel of therun of the sprocketchain-52 will move the pin 10 horizontally out of engagement :with thepin 67. The carriage is nowibeing .lshifted to the rightand the extremeright position is shown in Figure 4. When the extreme right position,Figured, is reached, the pin 59 is passing downwardly over the sprocketwheelz50, at which time the pin 59 will disengage the upper peg 51, andthe. carriage will be at rest, while the pin is traveling about thesprocket wheel:50. The pin fl is now in proximity to the bar68, whichhas been shifted to the right andwhen the pin travels downwardly aboutthe sprocket wheel 50, the pin engages the pin 69 of'the bar 68, duringthe rest periodof the carriage,

turning the .bar.68 and shaft SI and. effecting the next intermittentmovement of the feed roller When the pin59 againreaches the'loweredposition, it will engage behind the peg '58. and

the carriage is again shifted to the left and the operation is repeated.vIt is thus seen'that the carriage is shiftedtransversely in. one direc--tion and stopped, andthen the work is fed longitudinally .a step andthecarriage thenshifted transversely in the opposite direction andstopped and the .work fed a step, and this cycle ofjoperation isrepeated. This results in the intermittent longitudinal feedof the.fabric andbetween the intermittent longitudinalfeed, :the fabric'is'lshifted transversely with respect to the sewshown in Figure 8 isprovided, including" U- shaped portions having transverse portions-i5which aresewed into or over each, other.

I .1 alsorcontemplate operating the machine so -that the work may beprovided.with longitudinal lines of stitches 16 instead of transversestitches.

- :ro so this, the rotation of the shaft: is stopped and the shaft 61 iscontinuously driven, which a may be effected by a'gear ll mountedthereon The sewing machine then will produce the long tudinal continuouslines of stitching since the;

machine is used in this W y, I contemplate em;

ploying a sewing machine having a plurality bf needles sothat aplurality of lines of stitchesis produced at one time. The sewingmachineused to produce the trans verse and longitudinal lines of stitching hasthe ordinary feed dog mechanism removed, as feeding iseffected bytheshifting of thewor-k bodily bymeans of thecarriage and the in mittentrotatin of the feed rolls while the=swing machine remains stationary.Any suitable type of sewing machine may be employed which will sew andpermit of the work being shifted in different directions.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as the preferred example of the same and thatvarious changes in the shape, size and afrangement of parts may beresorted to without departing from the spirit of my invention or thescope of the subjoined claims.
